Telkom low internet (LTE) connection

I have a Telkom Mobile data contract (LTE), over the past three weeks or so I have been having connection issues with my download speed at 0.02mbps. this has been frustrating as I work from home and expect to be connected to be able to do my job productively. I have logged numerous queries with them and to date i have not received any feedback. what frustrates me most is that I have had to resort to changing service providers just to ensure I get coverage in the mean time however this is not conducive for me as I have had to pay extra money to buy data whilst I have data contract with Telkom. up on enquiry with their contact center agent I am told that the matter has been escalated to technicians but this is yielding fruitless results as my connection is not doing it for me.
